So, based on the discussion on Light Reading, Simon Saunders says the following:

However I've found one additional category helpful: "Meadowcell" to contrast rural public access small cells against their "metrocell" urban counterparts. And we've found certain regulators to be enthusiastic about the opportunities they bring. The electronics for 'meadowcells' may not be so very different from their metro counterparts though issues like backhaul may be. Its a trickier more diverse market, but given government incentives I think there is scope for the market to be comparable in size to the metro market - vendors should leap on it!
